Each of the persons $A$ and $B$ independently tosses three fair coins. The probability that both of them get the same number of heads is:

The probability that a marksman will hit a target is given as $1/5$. Then his probability of at least one hit in $10$ shots is:

An unbiased coin is tossed $8$ times. The probability that head appears consecutively at least $5$ times is

$A$ die is thrown $6$ times. If 'getting an odd number' is a success,what is the probability of $5$ successes?

Two dice are thrown successively $4$ times and getting a doublet is called a success. The probability of getting at least $1$ success is (in $/1296$)

$A$ box contains $24$ identical balls,of which $12$ are white and $12$ are black. The balls are drawn at random from the box one at a time with replacement. The probability that a white ball is drawn for the $4^{th}$ time on the $7^{th}$ draw is
